To save people time, I can tell you that (ATTOW) the answer seems NOT to be google.com/settings/takeout .. I have tried the "YouTube" 'product', and the "Google+ Pages" and "Google+ Stream" 'products', without success.

If the questions appear to be duplicates, isn't it correct to mark the newer question as the duplicate? This question is #25964 and the other #31960. I would've marked that one a duplicate.

BTW, it seems you can only view that info in "desktop mode".

Thank you! How do I arrive to that link from YouTube's user interface?

From your desktop browser from the top right, click on your user avatar/icon > My Channel > (left side under LIBRARY) History > on the right underneath History type select "Comments". Also please don't forget to up vote this answer as well as the question if you found this helpful. t

Yes, this works. Perhaps add a description and/or screenshots on how to get to the History page (hamburger menu on the left, select the appropriate history type from the radio buttons)?

It doesn’t seem to be a native way to do this. However, I found this eHow article that lists a few (cumbersome) methods for finding your comments.

Enter the username and click "Search comments." This is the one current YouTube feature that does allow direct username searches to find comments. However, only recent comments in the past few hours come back in the search. Use this on the same day of posting a comment before it exceeds the search result time limit.

Use the Favorites section to find comments on videos that the user marked as favourites. Log in with the "Sign In" link at the top and scroll over the username at the top of the page. Click on Favorites in the menu that drops down. This section links to the user's "favorited" videos, but the user must then click on each video and search through the comments to find his own comments. This section does not show all the viewing history of the user. However, the videos may contain many of the comments searched for because this lists the user's favourite videos.

Use the History section for a more thorough search. Log in with the "Sign In" link at the top. Click "History" at the top or scroll over the username at the top and click "Account." The Account section has a comprehensive list of features. Click "History" and visit each video to find comments.

Use the Video Comments feature in the Account section to find personal comments that have received a reply. Click on the list of replies and the video link in each reply to see the videos. Search the comments for the user's username to find comments. This is also a limited feature but shows some of the more active conversations involving the personal user.

ATTOW, there doesn't seem to be an "Account section" or anything else with a "Video Comments" feature. So bullet #4 may be out-of-date. The incomplete approaches in bullets #2 and #3 should still work, though the instructions for bullet #2 seem to be out-of-date.

this is a nice ideea and it works but ... ONLY AS LONG AS YOU HAVE A REALLY UNIQUE NAME, if your name is common enough, you may find millions of results with the same name and worse, with names that contain your name and the actual problem with this solution is the fact that comments don't contain the google/youtube id, but the full name of the user (id is unique, full name is not)

youtube.com/all_comments redirects to youtube.com. I don't know if that says anything, but is site:youtube.com/all_comments valid syntax?
– Peter MortensenAug 13 '19 at 11:59

This does not work at all. When I tried it, I got two complete unrelated search hits, "The A's - (12) A Woman's Got Power - YouTube" and "The A's - Words [1979] - YouTube".
